'1 Claims,

' This invention relates to a yar'n package, more particularly to the core upon which the yarn is packaged and has for one of its objects to provide means by which the remnants of yarn which is wound about the core maybe easily removed from the core.

Another object of the invention is to provide a core upon which yarn is packaged or assembled which is provided with a means for removing the last remnants of yarn from the core without injuring the core.

Another object of the invention is to remove the unused yarn woundupon a spool, bobbin. or the like, quickly and easily and without injury to the bobbin which is usually of wood or some fibre material.

With these and other objects in view, the in-- vention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawing:

Fig. l is a sectional view illustrating a spool equipped with my invention and showing the yam' cutting means in its initial position relativeto the spool, the cutting means being shown in dotted lines in its position after having passed thru the yarn on the spool.

Fig. 2 is an end view of the spool.

Fig. 5 is a sectional view of a braider spool and a modification as regards the showing in Figs. 1 to 3. i

Fig. 6 is an end view of the spool shown in Fig. 5.

Fig. '7 is a sectional view of a further modification and showing a loom bobbin for insertion in a shuttle also equipped with my invention.

Fig. 8 is a sectional view on line 8-8 of Fig. 7.

Spools, bobbins and the like upon which yarn is packaged by winding are usually formed of wood or fibre and the unused yarn which remains upon these spools or bobbins as the last remnants when the majority of the package has been withdrawn, is of an amount usually insufiicient to make practical the drawing off of this last remnant for use, consequently various means are employed for strippingcutting or tearing of! this unused yam which is waste so far as further textile operations are concerned and which usually is accumulated as cotton waste.

.The last unused remnants of yarn are removed from aloom bobbin or similar type core by causing a pair of gripping jaws to graspithe yarn by moving, toward each other and then moving axially of the core to pull the yarn from the core or in the case'of spools or sometimes the above mentioned loom bobbins the'operator may by using a knifev force the knife through the yarn against the wooden or non-metallic core and then draw the knife axially of the core to cut thru the remnants of the yarn, thereby incidentally cutting into the core so as to cause an abrasion of its surface.

All of these methods destroy or injure the smoothdesired finished surface of the core or flange of the spool or bobbin upon which the yarn is packaged which is undesirable and by the provision of the invention which .I have made this abrasion or injury of the core is eliminated.

I provide a slot in the surface upon which the yarn is wound and beneath the surface a guide whereby I may insert a knife which will project thru the slot and cut the yarn which is assembled upon the core ;from the ,-inside outwardly; This operation may be performed very simply and quickly and serves to completely sever the remnants ofyam on the core, permitting it to fall from the core as waste without injury of thecore, and the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these'advantageous results may be accomplished.

With references to the drawing, l0 designates the barrel ofa spoolusuallyformed of wood,

altho this may be formed of fibre or any other suitable material if desired. Heads II are positioned at the end of the barrel. A metal tube l2 extends centrally thru the barrel'and thru the heads and is flared outwardly asat l3 to hold the heads in position against the ends of the barrel. A slot ll is formed in the barrel extending lengthwise or axially of the barrel which connects with a hole I5 aso extending axially of the barrel and located inwardly from the outer surface of the barrel. A metal tube l6 forms a lining or bushing for this hole and is slotted as at I] to-register with the slot I! in the barrel. The heads-H are cut .out in 'a.

shape corresponding to the'opening Ii-and slot-s" l4, this slot .beingcontinued as-at'-I8;'".Suchopeningregisters with the slot)" and opening IS in the barrel. Slot l8 extends radialy o wardly from the center of the head to permit passage of the severing implement.

Yarn I9 is wound upon the surface of the barrel and over the slot which in no way interferes with the assembling of the yarn on the spool. The yarn initially fills the spool to substantially the full diameter of the heads ll. When unreeled, usually some feeler device will stop the operation of the machine just prior to the running out of the yarn l9 and there will remain on the spool an unused remnant of yarn l9 such as shown in Fig.1. The amount of this yarn is suflicient so that its removal is difficult but by use of a spool such as above described for assembling the yarn on I may insert a severing instrument which I have shown in Fig. 4 for the purpose of cutting and removing this yarn from the spool.

This severing instrument consists of a rod 20 bent as at 2| to provide a handle. Upon the shank portion in a suitable slot 22 I have fixedly mounted a knife 23 having sharpened edges 24 and 25. This knife 23 will be of substantially razor blade thickness and will possess extremely sharp edges. The end of the shank 20 is reduced as at 26 for the easy insertion into the opening l while the knife blade will be so positioned that it will extend into and thru slots l1, I4 and I8 sothat by merely pressing upon the handle the knife willpass length-.

wise of the spool and will cut thru all of the unused yarn which remains as a remnant thereon. This yarn will then fall from the spool as waste -and.the surface of the spool on which the yarn is wound will be uninjured and cleared. If, by chance, any of the yarns are not severed by the leading edge 25 of the implement as it passes thru theslot, the rear edge 2| will sever these yarns upon withdrawal of the implement thru the spool in its desired manner. 1

In the spool shown in Fig. 5 for the braider carrier, the barrel is designated 21 with heads 28 and 29 at either end which are integral with or all one piece with the barrel. The bushing 28 extends centrally thru the barrel and heads which is slotted as at 3| to register with the slot 3| in, the barrel. The slot 3| extends thru the heads as at 32, thus similarly permitting the insertion of a severing instrument such as shown in Fig. 4 thru the'center portion of the spool for severing any unused remnantof yarn which may remain thereon.

In Fig. 7 and Fig. 8 a loom bobbin 33, is illustrated as being provided for the usual enlarged gripped end 3| with aligning rings 35 thereon and this bobbin is provided with a central bore 36 which is lined with a bushing 31. This bushing is slotted as at 38 while the bobbin core is also slotted as at 39, this slot extending into the enlarged portion as at Ill so that a severing instrument maybe inserted in the bore 36 for the distance that the conically wound yarn remnant may occur and be guided thruthe slot 38, 39 and M so as to sever the yarn which maybe assembled thereon. i

The operations involving winding yarn on the core, whether they be spools, bobbins, or the like, are sometimes run at a very high number of revolutions per minute and balance of the core is necessary. In Fig. 1 there has been considerable removal of non-metallic or wooden material in the making of the hole l5 and slot ll and in order to compensate for this removal the weight of the lining or bushing It will be made equal to the amount of the removed stock so as to maintain the spool in perfect dynamic balance where high rotation is desired. In case of such spools as shown in Fig. 5, a means of dynamic balancing may be provided such as, for instance, adding weight to the spool where stock has been removed or by grooving or cutting stock from the spool on the opposite side of the slot for this purpose and this same will be true in Fig. 'l for the shuttle bobbin for purpose of winding the yarn upon this bobbin at a rapid rate. It will, of course, be clear that when the bobbin is in use in a shuttle that no balance is needed as the bobbin is then not rotating.

The foregoing description is directed solely toward the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. A core for a yarn package about which yarn may be wound comprising a cylindrical body part having an enlarged end portion, a slot extending through said enlarged portion inwardly of the periphery thereof and into the body part and opening into the outer surface thereof and through which slot a severing instrument may be passed.

2. A core for a yarn package about which yarn may be wound comprising ,a cylindrical body part having an enlarged end portion, a slot extending through said enlarged portion inwardly of the periphery thereof and into the body part and opening into the outer surface thereof and through which slot a severing instrument may be passed, and the side walls of said slot serving to guide the said instrument through said slot.

3. A core for a yarn package about which yarn may be wound comprising a V cylindrical body part having an enlarged end portion, a slot extending through said enlarged portion inwardly of the periphery thereof and into the body part and opening into the outer surface of the body part and through which slot a cutter may be passed, said slot being enlarged radially inwardly for guiding an instrument carrying the cutter projecting through said slot.

4. A core for a yarn package provided with a 'body portion about which yarn may be wound and flange portions, one at each end of the body with a slot extending the entire length of said core and opening into the peripheral surface of the body portion and extending'through' said flange portions inwardly of the peripheral surface of the flange portions and through which a severing instrument may be passed.

'5. A core for a yarn package about which yarn may be wound, comprising a body portion having an enlarged end portion, a hole located eccentric to the axis of the core extending through said enlarged end portion and into said body portion and inwardly from the periphery of both portions, a slot of less width than said hole connecting said hole to the outer surface of the body portion. said hole and slot being ofa size to accommodate a severing instrument for passage therethrough.

surface thereof and into said hole and extending in the same straight line through the'said enlarged end portion, through which slot 9, severing instrument may be passed, the side wall of said slot serving to guide said instrument through said slot, and a lining in said hole having a slot registering with said slot, said lining being of a weight to maintain the core insubstantially dynamic balance.
